This is a introductory video to a domain of Information technology that is Network security.
Definition of Network Security:
Network security is protection of the access to files, directories and information in a computer network against hacking, misuse and unauthorized changes to the system.
In this video tutorial the basics of Network security, some definitions, terms and concepts. We've also covered some types of attacks that take place when Network security is not implemented properly.

Python Tutorial for Beginners: https://goo.gl/cLKYQP
5 skills for IT Professional: https://goo.gl/ba6Ui7
Top 5 technologies to learn in 2018.
Technologies are :
IoT (Internet of Things)
Cloud Computing
Blockchain
Artificial Intelligence
Big Data
IoT : The Internet of things (IoT) is the network of physical devices, vehicles, home appliances and other items embedded with electronics, software, sensors, actuators, and network connectivity which enables these objects to connect and exchange data.
The IoT allows objects to be sensed or controlled remotely across existing network infrastructure.
Cloud Computing: Cloud computing enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet.
Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility.
Third-party clouds enable organizations to focus on their core businesses instead of expending resources on computer infrastructure and maintenance.
Cloud providers typically use a "pay-as-you-go" model.
Blockchain: A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography which is resistant to modification of the data.
Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data.
Blockchains are secure by design and are an example of a distributed computing system
The first blockchain was conceptualized in 2008 by an anonymous person or group known as Satoshi Nakamoto and implemented in 2009 as a core component of bitcoin where it serves as the public ledger for all transactions.
Artificial intelligence: AI is intelligence displayed by machines.
In computer science, AI research is defined as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of success at some goal.
Colloquially, the term "artificial intelligence" is applied when a machine mimics "cognitive" functions that humans associate with other human minds, such as "learning" and "problem-solving
Big Data: Big data is data sets that are so voluminous and complex that traditional data processing application software is inadequate to deal with them.
Big data challenges include capturing data, data storage, data analysis, search, sharing, transfer, visualization, querying, updating and information privacy.
There are three dimensions to big data known as Volume, Variety and Velocity.

firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. a firewall typically establishes a barrier between a trusted internal network and untrusted external network.
Firewalls are often categorized as either network firewalls or host-based firewalls.
Network firewalls filter traffic between two or more networks and run on network hardware. Host-based firewalls run on host computers and control network traffic in and out of those machines.

EE380: Computer Systems Colloquium Seminar
The Evolution of Public Key Cryptography
Speaker: Martin Hellman, Stanford EE (Emeritus)
While public key cryptography is seen as revolutionary, after this
talk you might wonder why it took Whit Diffie, Ralph Merkle and
Hellman so long to discover it. This talk also highlights the
contributions of some unsung (or "under-sung") heroes: Ralph Merkle,
John Gill, Stephen Pohlig, Richard Schroeppel, Loren Kohnfelder, and
researchers at GCHQ (Ellis, Cocks, and Williamson).

This is a written version of Martin Hellman's ACM Turing Lecture
(https://www.youtube.com/watch?v=I132wSwAI3o) and was accompanied by a
short (6 minute) video (https://vimeo.com/241030842).
Other materials and hard to find references can be found on Martin
Hellman's Stanford website, http://www-ee.stanford.edu/~hellman/ .
About the Speaker:
Martin E. Hellman is Professor Emeritus of Electrical Engineering at
Stanford University and is affiliated with the university's Center for
International Security and Cooperation (CISAC). His recent technical
work has focused on bringing a risk informed framework to a potential
failure of nuclear deterrence and then using that approach to find
surprising ways to reduce the risk. His earlier work included co-
inventing public key cryptography, the technology that underlies the
secure portion of the Internet. His many honors include election to
the National Academy of Engineering and receiving (jointly with his
colleague Whit Diffie) the million dollar ACM Turing Award, the top
prize in computer science. His most recent project is a book, jointly
written with his wife of fifty years, "A New Map for Relationships:
Creating True Love at Home & Peace on the Planet," that provides a
"unified field theory" of peace by illuminating the connections
between nuclear war, conventional war, interpersonal war, and war
within our own psyches.

APL Computer Science and Engineering Seminar Series
"On-line patching for better security, and other security challenges"
Michael W. Hicks
Professor Michael W. Hicks' research focuses on developing programming language technology to help programmers build software that is available, reliable, and secure. In this talk he will present an overview of his interests and general approach, details on one research direction, and highlights of the Maryland Cybersecurity Center (MC2).
The first half of the talk describes his recent research on dynamic software updating (DSU). For systems that require (or would prefer) continuous operation, software updates to fix bugs and vulnerabilities or upgrade functionality create a problem, as updates normally require a shutdown and restart. DSU addresses this problem by allowing updates to be applied without shutting the system down. Dr. Hicks has recently developed a system called Kitsune for supporting DSU in C programs. Kitsune is flexible, efficient, and relatively easy to use: it has been used to support more than 40 release-level updates to six popular C server programs while requiring few code changes, and imposing no overhead to normal execution.
The second portion of the talk describes the Maryland Cybersecurity Center and the research and education activities taking place there, which cover topics including system security, software security, resilient distributed systems, game theory, applied cryptography, network forensics, security economics, and supply chain security, among other topics.
Bio:
Michael W. Hicks is professor in the Computer Science department and UMIACS at the University of Maryland, College Park, and is the Director of the Maryland Cybersecurity Center (MC2). His research focuses on using programming languages and analyses to improve the security, reliability, and availability of software. Noteworthy among his research accomplishments is the development of analysis and compilation tools for enabling software to be safely updated while it runs. He has explored the design of new programming languages and analysis tools for automatically discovering or remediating software flaws and security vulnerabilities. He has recently been exploring new approaches to privacy preserving computation, and means to debug programs more effectively.
